The great sage Narada Muni was a naisthika-brahmacarithat is, he never had sex life. He was consequently an ever-green youth. Old age, jara, could not attack him. The invalidity of old age can overcome an ordinary man, but Narada Muni was different. Taking Narada Muni to be an ordinary man, the daughter of Time confronted him with her lusty desire. It requires great strength to resist a womans attraction. It is difficult for old men, and what to speak of young. Those who live as brahmacaris must follow in the footsteps of the great sage Narada Muni, who never accepted the proposals of Jara. Those who are too much sexually addicted become victims of jara, and very soon their life-span is shortened. Without utilizing the human form of life for Krsna consciousness the victims of jara die very soon in this world.
